Say to My servants that they should (only) say those things that are best: for Satan doth sow dissensions among them: For Satan is to man an avowed enemy. 53 Your Lord is the Best Knower of you; if He willeth He will have mercy upon you, or if He willeth He will torment you. And We have not sent thee over them as a trustee. 54 And your Lord knows well all those who are in the heavens and the earth; and indeed among the Prophets We gave excellence to some above others, and We gave the Zaboor to Dawud. 55 Say: 'Call on those you asserted apart from Him; they have no power to remove affliction from you, or to transfer it. 56 Those they call upon are themselves seeking the means to come to their Lord, which of them shall be nearer; they hope for His mercy, and fear His chastisement. Surely thy Lord's chastisement is a thing to beware of. 57 No city is there, but We shall destroy it before the Day of Resurrection, or We shall chastise it with a terrible chastisement; that is in the Book inscribed. 58 And We refrain from sending the signs, only because the men of former generations treated them as false: We sent the she-camel to the Thamud to open their eyes, but they treated her wrongfully: We only send the Signs by way of terror (and warning from evil). 59 When We said to you: 'Indeed, your Lord encompasses all people' We did not make the vision which We showed to you, and the tree cursed in the Koran except to be a trial for people, and We frighten them, but it only increases them in great insolence. 60
